Abstract

Human neutrophils are able to kill in vitro colorectal carcinoma cell line SW11-16 coated with mAb 17-1A, but they are not cytotoxic towards a non-immunized tumour target. Neutrophil exposure to the inflammatory cytokine, IL-8, produces a significant increase in antibody-dependent cellular cytotoxicity, which is related to IL-8 concentration. Oxyradical production is one of the lytic mechanisms used by phagocytes, and IL-8 is shown to activate this function, which does not occur if neutrophils are pretreated with the protein kinase C inhibitor, staurosporine, but is increased by R9022, a dyacylglycerol kinase inhibitor. The IL-8 effect is mediated by protein kinase C, which is potentiated by the calcium nux induced by the interaction between antibody coating tumour target and FcγRIII on effector cells, as previously demonstrated. Data suggest a possible new role for IL-8 in tumour surveillance.
